    Abstract: This application provides a congestion control method and a network device. The method includes: receiving a first message sent by a second network device, where the first message carries an active flow quantity, and the active flow quantity is a quantity determined by the second network device based on a data flow to which data packets received from a first network device belong; determining, based on the active flow quantity and rated receiving bandwidth of the second network device, packet sending control information used to send the data flow to the second network device; and sending the data flow to the second network device based on the packet sending control information. This application can better control congestion, thereby reducing network packet loss.

    Abstract: A network congestion control method includes, during transmission of a first service flow, a first network device that obtains a measurement packet including groups of measurement results corresponding to the first service flow, and each group includes an identifier of a forwarding device on a forwarding path of the first service flow and a measurement value corresponding to the forwarding device. The first network device determines, based on the groups, a congested second network device on the forwarding path. The first network device determines a control policy based on location information of the second network device, where the control policy resolves congestion of the first service flow.

    Abstract: A data processing method implemented by a controller includes after receiving a processing request from a specified node carrying identifiers of a plurality of computing nodes configured to execute a specified calculation task, determining a target switching device from switching devices that are configured to connect to the plurality of computing nodes, and separately sending, to the target switching device and the specified node, routing information used to indicate data forwarding paths between the plurality of computing nodes and the target switching device. The target switching device is configured to combine, based on the routing information, data reported by the plurality of computing nodes, and then send combined data to each computing node. The specified node is configured to send the routing information to each computing node, and each computing node may report data to the target switching device based on the routing information.
